Description

The invention relates to emergency evacuation devices and is intended primarily for lowering people from buildings with a mechanical braking mechanism.

A rescue device is known that contains a safety cable with a carabiner, a fixing unit in the form of a belt with a buckle, in which a reserve of the safety cable is located, and a brake mechanism located on the cable between the fixing unit and the carabiner (see RU 2422174, class А62В 1/10, publ. 06/27/2011). The disadvantages of the known device are the inconvenience of use and unreliability of the braking mechanism, as well as a complete failure when the cable breaks.

The objective of the invention is to remedy these disadvantages. The technical result consists in increasing the reliability of the rescue device. The problem is solved, and the technical result is achieved by the fact that the rescue device containing the safety cable with a carabiner, the fixing unit in the form of a belt with a buckle, in which the reserve of the safety cable is located, and the brake mechanism located on the cable between the fixing unit and the carabiner, contains a second a safety cable located similarly to the first one, and the brake mechanism is made in the form of a separate housing containing guide channels and wedge-shaped brake elements and providing independent braking about oih rescue ropes, wherein between the brake mechanism and the outlet of the belt buckle rescue ropes last passed through the flexible tube. An adjustable strap is preferably attached to the belt, which, if necessary, is passed between the legs of the user. The brake mechanism is preferably provided with an electronic unit, providing the ability to control the braking force and / or transmission of information messages. The stock of each safety cable can form a knitted product made with pre-tensioning the cable, or it can be located in the belt by ordered laying without looping. The stock of each safety cable can be laid in a case. Each safety cable is preferably coated with a polymer, for example, polyurethane with a high degree of adhesion to the safety cable. Each safety cable is preferably entwined with a heat-resistant and wear-resistant protective element made in the form of monofilament, fiber, non-woven material or additional cable. Each safety cable can be made in the form of any of monofilament, fiber, non-woven material, spun monofilament, spun fiber, spun non-woven material or woven from these elements with the formation of a woven material in which the components of the cable at the points of mutual contact are additionally fastened with adhesive material, sewing or ermicheskoy welding. Through fastening, each safety cable can unfold from a woven material with an effort that partially compensates for the action of the braking mechanism. The rescue device may contain additional reserves of safety cables, formed in the form of one or more elements or parts of elements of clothing or shoes, for example, pockets, gloves, headgear, bag, backpack.

Figure 1 presents a General view of the proposed device in operating position;

figure 2 is a section aa in figure 1;

figure 5 is a brake mechanism of the device in section, side view.

The rescue device includes a belt 1 with a size-adjustable buckle 2 and an adjustable belt 3, which, if necessary, is passed between the legs of the user, for fixing the size-rescued “U” or cargo through the latch 4.

In belt 1 there are two open stocks of rescue cables 5, which are enclosed in a protective fabric cover 6 and separated by a flexible or rigid gasket 7. Rescue cables 5 exit the belt 1 in the buckle zone 2 and pass through two flexible tubes 8, placed in the mandrel 9, through the braking mechanism 10. This section of the device is necessary both to hold the rescued and to protect the cables from damage. At the end of the cables 5 after the brake mechanism, a carabiner 11 is installed to secure the cables in the abandoned room.

The brake mechanism 10 contains guide channels 12 and wedge-shaped brake elements 13 located therein, which provide reliable (more reliable than the brake rollers used in the prototype) and independent braking of both rescue cables 5. The brake elements 13 clamp the cables 5 under the action of the cam lever 14, and the initial force is regulated by screws 15. The position of the lever 14 is determined by the ratio of the forces on the return spring 16 and the flexible control cord 17. The brake mechanism 10 can be additionally attached to the belt 1 eye tool 18.

The brake mechanism 10 performs the following functions:

- regulates the speed of descent from 0 to 2.5 m / s;

- ensures the operation of cables and stops movement in the event of a break;

- serves as an element of insurance and withholding from the coup saved;

- serves as a housing for installing the electronic unit of the information and notification system.

For compact placement and avoid entanglement, the supply of each safety cable can form a knitted product made with pre-tensioning the cable, or it can be located in the belt by an orderly laying without loops. In addition, the rescue device may contain additional reserves of safety cables, formed in the form of one or more elements or parts of elements of clothing or shoes, for example, pockets, gloves, headgear, bag, backpack.

To prevent abrasion, each safety cable is preferably coated with a polymer, for example, polyurethane with a high degree of adhesion to the safety cable. To ensure safety in extreme conditions, each safety cable 5 is entwined with a heat-resistant and wear-resistant protective element made in the form of monofilament, fiber, non-woven material or an additional cable. To provide the possibility of completing the device with several weight ranges, for example 50-80; 80-100, etc., the safety cables 5 are made in the form of monofilament, fiber, non-woven material, spun monofilament, spun fiber, spun non-woven material or woven from these elements with the formation of a woven material having the corresponding strength characteristics, in which the components of the cable in the places of mutual contacts are additionally fastened with adhesive material, sewing or thermal welding. Through fastening, each safety cable can unfold from a woven material with an effort that partially compensates for the action of the braking mechanism.

The device operates as follows.

In the event of an emergency leading to the need, for example, evacuation from a building from a high height, belt 1 and belt 3 are attached to the user (in this case, a device with a cable of the required weight range is selected). Then, with the help of a carabiner 11, the ends of the safety cables 5 duplicating each other are attached to a heating pipe, a bulky object, or another accessible fixed interior element. Then carry out the descent. The speed of movement up to a complete stop is regulated by the tension of the control cord 17, which transfers the load through the wedge-shaped brake elements 13 to the cables 5 clamped in the channels 12.

The small size and simplicity of the design of the proposed device allows you to always carry it with you, ensuring the safety of its owner in extreme conditions. The invention is not limited by the given example of its implementation and can also be used in other critical situations requiring the use of a durable lightweight cable of great length (lowering and lifting people in the mountains, etc.).
